The two charred bodies were found in the trunk of a car on an overpass across the E6 motorway near Getinge outside of Halmstad late in the evening on January 6th.
Only one of the victims has been positively identified, the 25-year-old son of the vehicle’s owner.
The other victim is thought to be a 42-year-old man.
The 35-year-old, who has a warrant out for his arrest on suspicions of murder, came to the memorial service in Värmland in western Sweden and introduced himself as a friend of the victims, TV4 reports.
“He came here, we listened to him and consoled him when he cried,” the 42-year-old’s brother told the local TV4 affiliate.
According to the police, there is a connection between the 42-year-old and the 35-year-old suspect.
Police believe the victims were killed with aggravated violence on a farm between Genarp and Dalby in Lund municipality.
Investigators also suspect that several people were involved in the killings.
A large pile of dirt has been taken from the murder scene, most likely on a trailer, to hide evidence that may have been left at the scene.
The 35-year-old has previously been convicted of several drug and traffic violations. He was also caught by customs officials in mid-September attempting to bring a small amount of cocaine across the Öresund Bridge in a case which has yet to be closed.
